  • Driving system with converter control for low-voltage three-phase motors
    Patent number: 7006356
    Abstract: Driving system with converter control for low voltage three-phase motors, which is provided with a power unit containing transistors and capacitors, a triggering unit for the transistors and a control unit as well as connections for direct and alternating current, the units being disposed in a common casing made of a heat-conductive material, characterised by the following features: the power unit is provided with a first printed circuit board (24) made of fairly heat-conductive material, which is disposed on the fairly heat-conductive bottom of the casing (12) in a plane fitting arrangement, a second printed circuit board (26) contains the triggering unit, the second printed circuit board (26) being electrically and mechanically connected to the first printed circuit board (24) in a spacing to it with the aid of contact pins (30) of metallic material attached on the first printed circuit board (24) by soldering, and terminal pins (22) are connected with contact points (38) of the first printed circuit board
